3. STATEMENT OF RESEARCH My primary research interests and expertise are in experimental studies of reservoir processes and subsurface hydrology in porous and fractured media, including multiphase flow, phase dissolution and mass transfer, interfacial and wetting phenomena, rock mechanics and coupled THMC fundamentals. These experimental studies are motivated by the need to better understand processes controlling geological CO2 sequestration, spent nuclear fuel and waste disposal, shale gas & oil, and geothermal energy production. At LBNL, I work on (1) nanomaterial synthesis and application for investigating subsurface energy production (oil & gas, geothermal, etc.); (2) pore-scale supercritical CO2-brine displacement, including mass transfer and interfacial wetting effects under reservoir high pressure and high temperature conditions, using 2D micromodels, facilitated with fluorescent tracer dye and microscope imaging; (3) core-scale multiphase flow and rock mechanics with X-ray

CT imaging and customized triaxial loading system, (4) bench-scale investigations of coupled THMC processes in engineered (clay) barrier systems and engineered (bedrock) damage zones for ensuring the safe and long-term performance of geological disposal of spent nuclear fuel and waste.
